Apgilication filed August 29, 1911. Serial No. 646,632.

My invention relates to loom heddle frames, and it has particular relation to that type ofheddle frames in which the end z-ailsj made of relatively narrow material, for example, of the type shown in my previous Letters Patent No. 980,285, dated Jan. 3, 19.11.

as is well known. the heddle frames are mounted in the loom in close relationship to each other and are rapidly reciprocated up and clown pasteach other to form the sheds for the purposes o1 weaving. It has been found in practice that Where the heddle frames are constructed with the end bars made of relatively narrow material that the top and bottom rails frequently foul each other on account of the outer corner of one of the top orbottom rails catching under the inner corner of the top or bottom rail of the adjacent frame. This disadvantage is not found where the heddle frames are made with the end rails of relatively wide mate rial, that is to say, of a width greater than the possible sidewise displacement of the Frames with respect to each other, as in this case the faces of the end rails will effectively prevent the fouling. I

T he principal object, therefore, of my present invention is to provide a simple and efficient means for preventing the fouling of the adjacent heddle frames in the loom where the same are made with the end rails of relatively narrow material. 7

The nature and characteristic features of my invention will be more readily understood :t'rom the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure l a front elevation of a heddle frame embodying the main features of my present invention; Fig. 2 is an enlarged fragmentary elevation of one of the corners of the' frame; Fig. 3 is a transverse section, enlarged, of portions of two adjacent heddle frames in juxtaposition, showing how my 'improved means acts to prevent fouling of the too and bottom rails of adjacent frames in a loom; Fig. 4 is a View similar to Fig. 2 but showing a modified form of my.inven IGNOB TO s'rEEh HEDDLE' Patented Nov. 4, 1913.

tion; Fig. 5 is a perspective view of an ele ment constituting a simple form of device adapted to be attached to a heddle frame.

for carrying out my invention, the same being shown in its initial form before being;

mounted in the frame; and Fig. 6 is a perspctive View of a form of bracing member.

for the end rails h-avingwings integrally formed thereon for the purpose of carrying out my invention, the same constituting an alternative form of device for'efiecting the purpose. i

Referring" to the drawings, in the particular embodiment of. my nvention therein shown, the heddle frame comprises the top and bottom horizontal rails 7 and 8"which Q i may be made of th e iisual wood strips having roundededges, and these top and bottom rails 7 and 8 are joinedat'their endsby' means of the end rails 9 and 10 preferably" made of bar iron, which extendacro'ss the end faces of the top and bottom rails 7 and 8 and are bent over and secured on the outer sides of said top and bottom rails as at 11 by means of screwsor other suitable fasten ing means. The endrails 9 and 10 are secured to the top and bottom rails 7 and 8 at the inner corners thereof by means of bracing members 12 which may if desired be constructed and arranged as shown in my previous Letters Patent No."980,285, or in any other suitable manner. As shown in Figs. '1 and 2 the bracing members 12 comprise plates secured by screws or otherwise to the inner sides of the top and bottom rails at the ends thereof, and having re cessed portions for engaging slots in the end rails 9 and 10. The heddle. bars 14 and 15 upon which the heddles 16 are mounted are carried in the end bars 9 and 10 in any suit able manner, the arrangement ,being such that the ends of the-:heddles "are arranged a slight distance from the inner sides of. the v top and'bottom rails 7 and 8. Each of the bracing members 12 also serves to maintain a guiding device 17 in place'at each inner corner of the heddle frame and as showna V shape so as to pro- .tnred as at'QO for the one of the top or bottom rails to catch on the top or bottom rail of an adjacent frame will be counteracted by the inclined guiding surfaces as clearly shown in F ig. 3 of the drawings. As shown in Fig. 5'the guiding device 17 may be made initially of U shape in cross 1 section with straight wings 19 and apcri passage of the fastening screw of the bracing member 19. After I the bracing member is fastened in place by j means of the screw 21, the side wings are bent to the v shape as shown. in 'Fig.- 3 of. the drawingsand in dotted lines in Fig. 5. 1 Instead ofemploying the separate device i 17 for guiding the corners of the adjacent I frames as shown in Figs. 1 to 3, the bracing 1 member 12 may be provided with integrally J formedconvergin'g sidewings 2:2 as clearly shown in Fig. 6 of the drawings. it should i also be understood that instead of inountin the guiding devices at the inner corners I o the top and bottom rails, the same may be l l mounted at the outer corners thereof under.

the turned over ends 11 of the end rails as clearly shownin F ig. 4 of the drawings.

It will be seen that by the foregoing arrangement there is provided a simpie and efiicient device for preventing fou ing of the heddle frames which has heret. a great objection to the, form of made with the end rails of fiat rchu .iI) narrow metal and having ends bent over and secured on the outer. sides of the top and bottom rails. it should be noted, that i tors Patent is zontal rails and harm in the construction of frames Where the end rails and the employment of the bracing members which have been found essential in this form of construction. It will, of course, be understood that where bottom rails are made with the flat edges that the device of my present invention may be employed to prevent fouling at other points on the length of the top and bottom rails.
